により局線Ｂの切替／解除も前述と同様である。(Background Art) This type of line switching system will be explained using an example in which a central office line connected to a central office line trunk of a private branch exchange is disconnected from the private branch exchange and switched to a direct telephone line at night, on holidays, etc. . Figure 1 is a block diagram of the central office line switching system in a conventional private branch exchange, where EXT is the extension subscriber, LC is the subscriber circuit provided for the subscriber, COT is the central office trunk, and TRU i
is a switching circuit that switches the central office line between the exchange side and the direct telephone side, ORT is the outgoing register trunk, NW is the call path switch, and CONT is the control device that controls the switching operation. is being monitored. SW- is a changeover switch compatible with TRU-, and SWSCN is a scanning device that displays the ON/OFF status of SW- to CONT based on instructions from CONT. FIG. 2 is an explanatory diagram of TRU-, where T is a switching relay controlled by CONT. Usually, it is connected to the exchange through the central office line - TRU T-break contact - COT.
Now, if you want to switch the central office line A to the direct telephone line,
Turn on SWO. CONT is a constant time period.
Since the status of SW− is read via SWSCN, it is possible to identify that SWO has changed from OFF to ON.
Activate the T relay of TRU 0 that supports SWO and switch the office line A to the direct telephone side. On the other hand, if you want to switch (return) the switched central office line A to the exchange side, if you turn SWO off, CONT will turn off in the same way.
Identifies that SWO has changed from ON to OFF and sets TRU 0
Restore the T relay. Also, SW 1 ON/OFF
The switching/cancellation of the central office line B is also the same as described above.
尚、局線Ａと局線Ｂを同時に切替／解除する場

替方式にある。(Problems to be solved by the invention) An object of the present invention is to solve the above-mentioned problems of the prior art and provide a more effective line switching system. In an automatic exchange having a switching circuit for switching a line between an automatic exchange and a direct telephone set, and a control device for controlling the operation of the switching circuit, the control device is configured to control the operation and recovery of the switching circuit. It has a means for storing a predetermined line switching identification number, and the controller compares the numerical information sent from an extension or outside line connected to the automatic exchange with the pre-stored line switching identification number. If they match, there is a line switching system in an automatic exchange in which the operation, restoration, and switching of the switching circuit are controlled by instructions from the control device.

憶させている他は第１図と同じである。(Structure and operation of the invention) FIG. 3 is an embodiment of the present invention, and is a block diagram of a central line switching system in the aforementioned private branch exchange. In Figure 3, the operation identification number for TRU 0 corresponding to station line A is "70", the recovery identification number is "80", and
This is the same as in FIG. 1 except that the operation identification number for TRU 1 corresponding to station line B is stored as "71" and the recovery identification number as "81".

“81”により行う。 Now, the operation of switching the central office line A from the extension subscriber (EXT) accommodated in the private branch exchange to the direct telephone side will be explained. The control device (CONT) can learn from the subscriber circuit (LC) that the extension subscriber (EXT) has gone off-hook using a known method.
Connect the extension subscriber (EXT) and the originating register trunk (ORT) via a call path switch to prepare for dialing from the extension subscriber (EXT). Next, the extension subscriber (EXT) dials the identification number "70" to switch the office line A to the direct telephone side.
CONT receives the identification number from ORT, uses a known number translation method to verify that the number is the number that operates the switching circuit (TRU 0 ) corresponding to station line A, and when a match is found. Activate the T relay of TRU 0 to switch the office line A to the direct telephone side. On the other hand, central office line A switched to the first-party direct dial telephone side.
When switching (back) to the exchange side, the recovery identification number “80” from the extension subscriber (EXT) is also sent.
The T relay of TRU 0 is restored by receiving and identifying it. Operation and recovery control for TRU 1 corresponding to station line B is performed using identification numbers "71" and "81" as described above.

よび“81”に限定されるものではない。 Although this embodiment shows a case where the extension subscriber performs the dialing operation for switching, it is also possible to do this by receiving a line switching identification number from an external line (dedicated line, etc.) connected to the exchange. Of course, the identification number is not limited to "70", "71", "80" and "81".
